BRAKE ATTACHMENT or MOLINE, ILLINOIS.

FOR MOTOR VEHICLES.

Application filed November 5, 1924. Serial No. 747,904.

To all 107mm may concern:

Be it known that 1, WILLIAM A. PARTIE, a citizen of the United States,residing at )Ioline, inthe county of Rock Island and State of Illinois,have invented certain new and useful Improvements in :1. Brake,Attachment for Motor Vehicles, of which the following is aspecification.

My invention has reference to abrake attachment for motor vehicles, andhas for its purpose to provide a means for automatically operating thethrottle valve in the feed intake pipe of the motor, coincidently withthe action of the brake lever in reducing the speed of the car. In theoperation of a motor vehicle, it is usual to accompany the applicationof the brake with a shifting of the hand control of the throttle, so asto partially or wholly interrupt the supply of fuel to the engine. It issometimes inconvenient or diflicult to do this at the same time as thebrake is set, or the operation of the valve is overlooked, so that theengine continues in operation, and the power thereof is directed againstthe restraining force of the brake. By the use of the presentinvention'it is impossible for this to happen.

In the drawings: 1

Fig; 1 is a plan view of a motor and appurtenant parts, with theinvention'adapted thereto.

Fig. 2 is a detached view of the bracket Fig. 3 is a detail of the brakeconnection therefor.

A fragmentary part of a motor vehicle frame is indicated by thereference number 1, upon which frame is mounted a motor 2. 3 representsthe brake pedal, mounted in rear of the motor in the usual manner, andat the opposite side of the engine is the carburetor 4 and fuel intakepipe 5, within which is the usual throttle valve, (not shown in thedrawings) under the control of a lever 6 which is connected by a rod 7with the throttle rod to be found on the steering column of motorvehicles, and which is actuated by the hand of the operator. By thismeans the supply of fuel gas to the engine can be controlled.

Fulcrumed .on the upper side of the motor, as at a, is a lever 8, atoneend of which is a sleeve 9, slidable on a rod 10, which has a hingedconnection with a shoe 11, clamped to' the tread .of the pedal" 3.

pedal, and

The other'end of the lever '8 is connected by a link 12 with an arm 18on the upper end of a vertical rod 14, supported by a a plate 16,secured to the frame 1, and at its upper end with a plate 17', attachedto the engine casing. The rod-14 ispivotally held in the plates 16 and17, and is provided at its lower end withan arm 18, connected .by a link19 with the lever 6.

bracket 15, provided at its lower end with A sleeve 20 is attached .tothe rod 10 by means of a set-screw, and between said sleeve and thesleeve 9 is supported on said rod an extensile coiled spring 21. iVhenthe pedal 3 is operated to set the brake the rod 10 is moved forward,first compressing the spring 21, and then causing a movement of thelever 8, as shown in 1 of the drawings. The movement of imparted throughtherod 14 o the lever 6, .causing a movement thereof in a directiontending to close the valve which is con trolled thereby, in the pipe 5.The rod 7 and lever control at the opposite end thereof, follows themovement of the lever 6. By this means the action of the brake pedal isaccompanied by a shutting off of the fuel supply, without any specialattention thereto by the operator. 7

. When the pedal 3 .is returned to its normal position, the sleeve 9 isfree to move 1e lever 8 is parts will respond readily to of the throttlelever on the steering post,

'and this movement returns the lever 8 to a position ready to beactuated by the next movement of the brake pedal.

The spring 2l-prevents any sudden jar or shock to the parts upon thebrake pedal being operated, and the tension of the spring can beregulated by adjustment of the position of'the sleeve 20 upon therod 10i If desired, the casing 11 may bfitted with a pad 22 of rubber orsimilar material, to prevent the foot from slipping-therefrom.

It will be understood that the showing of the invention in the drawingsherein is for the purpose of illustration, and that the same can bechanged in construction and arrangement of parts, so as to' adapt it toother types of motors, without departing from thespirit of the inventionas set forth and claimed herein.

7 What I claim, and desire to secure by Letters Patent, is:

1. In combination with the motor of an automobile, and brake pedal inroximity thereto, a rod hingedly attached to said brake pedal; a leversupported transversely of' said motor and provided on one of its endswith a sleeve slidable on said rod; a

contact member fixed on said rod, adapted for engagement with saidsleeve; and means of connection between the opposite-end of said leverand the throttle valve of the motor, so as to actuate said valvecoincidently with the movement of said brake pedal.

2. In combination with the motor of an automobile, and brake pedal inproximity therewith, a. rod' 'hingedly connected with the brakepedal; alever fulcrumed vabove said motor so as to extend transversely thereof,and provided at one of its ends with a sleeve slidable on said rod; acollar adjustably connected with said-rod-,-and capable of im artingmovement to said lever upon said rake pedal being actuated; a shockabsorbing element between said collar and said sleeve; and means ofconnection between the opposite end of said lever and the throttle valveof the motor.

In testimony whereof I afiix my signature.

WILLIAM PARTIE.
